The Verdict is In: Why Apple's C1 Modem Was Rated as "Terrible"

Apple's C1 Modem: A Rocky Start for In-House 5G

Apple's ambitious move to create its own mobile device modem, the Apple C1, marked a significant shift in the company's strategy. Debuting in the iPhone 16e, the C1 aimed to reduce Apple's reliance on external suppliers like Qualcomm, a major player in the modem market. This bold step, however, has faced unexpected challenges. Early reviews and analyses have painted a less-than-positive picture of the C1's performance, raising questions about Apple's in-house modem capabilities.

Early Reviews: A "Terrible" Start for Apple's C1 Modem?

Initial performance tests revealed that the Apple C1 modem significantly lags behind Qualcomm's competing solutions. A detailed analysis of the C1's die shots by tech expert LITTERTREE66 further underscored these concerns. Their assessment of the modem's PPA (Power, Performance, and Area) was exceptionally critical, labeling it "terrible." A Weibo post, translated from Chinese, summed up the sentiment: "Except for saving energy, it has no advantages, and I hope that the C2 will have a surprise."

A key factor contributing to the C1's poor performance is the absence of mmWave support. Renowned tech analyst Ming-Chi Kuo reported that Apple originally intended to integrate mmWave 5G technology into the C1. mmWave is essential for achieving incredibly fast 5G speeds, particularly in congested areas like city centers and stadiums. However, Apple apparently encountered significant difficulties in implementing mmWave without severely impacting the modem's power consumption. This hurdle ultimately resulted in the exclusion of mmWave from the C1's features.

Hope for the Future: The Apple C2 Modem

Despite the C1's disappointing launch, reports suggest that Apple's next-generation modem, tentatively named the C2, is poised to address many of its predecessor's shortcomings. The C2 is expected to offer significant improvements in power efficiency, data transmission speeds, and crucially, mmWave 5G support. Rumors even suggest that the C2 could power Apple's flagship iPhone 18 Pro models, potentially replacing Qualcomm modems entirely in Apple's premium devices.

Apple reportedly aims to surpass Qualcomm's modem performance by 2027. However, the C1's current performance highlights the considerable challenges Apple still faces in achieving this ambitious goal. In the meantime, it's possible that the C1 modem may find its way into future entry-level iPad models.

The iPhone "e" Series and Future Modem Choices

The release of the iPhone 16e also marked a significant change in Apple's budget-friendly iPhone SE line. The rebranding, linking the "e" models to the current main iPhone generation, has sparked speculation about the potential for annual releases of "iPhone e" devices. If this pattern continues, it will be fascinating to observe which modem Apple chooses for a hypothetical iPhone 17e in 2026. The ongoing development and performance of Apple's in-house modems is a story that will continue to unfold in the years to come, captivating the attention of the tech world.

The initial performance of the C1 modem is a clear indication that Apple's journey to creating a truly competitive in-house modem is far from over. While the C2 promises significant improvements, the timeline for Apple fully replacing Qualcomm remains uncertain. This ongoing saga is definitely worth watching for anyone interested in the future of mobile technology.
